JAMES M. HALLOVVES, OF NEW YORK, N. Y.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 383,728, dated May 29, 1888.

Application filed November 2, 1887. Serial No. '254',09E 1. (No model.)

To all whom it may concern.-

Be it known that I, JAMES M. HALLOWES, of the city, county, and State of New York, have invented certain new and useful Improvements in Car-Axle Boxes, of which the following is a specification, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention is to render earrc axle boxes dust and oil tight, to provide an. end stop for the axle within the box, and

also to improve the lubricating devices; and

my invention consists in the improved construetion and arrangement of parts, as will be hereinafter set forth.

In the accompanying drawings, Figure 1 is a longitudinal section showing my invention. Fig. 2 is a transverse section. Fig. 3 is a sectional plan. Fig. 4 shows a modification.

Similar letters of reference indicate similar parts in the respective figures.

A is an axle-box, of which a is the door. This door has a lug or ear, a, projecting into the box, which lug has a tapered hole, a.

B is a bolt which is screw-threaded at its upper end and passes through a hole in the upper face of the box, through the tapered hole a, and also through a hole in a lug, a, which forms part of the axle-box. When the bolt Bis screwed home, it draws the door a tightly against the box A and holds it firmly in that position.

The back end of the axlebox is cut out to receive the revolving plate 0. This plate 0 is made to revolve with the axle by means of the screw 0, which passes through the plate into a slot, 0, in the packing-ring O, which fits tightly on the axle. The object of this slot is to allow the axle to have longitudinal o movement in the box. The plate Ois held against the plane of the back end of the axlebox by means of the spring D between the hub of the wheel and the plate (3.

E is an end stop for the axle, which is pivoted on the inside of the axle box by means 5 g, attached to the side of the axle-box by means of the bolts g.

The operation of this device will be apparent from the foregoing. It will be seen that it possesses the advantages of simplicity, effectiveness, and strength.

Having described my invention, I claim- 1. The axle-box A, having the perforated lug a, combined with the door (1, having the lug a, provided with the tapered hole a and the screwbolt B, substantially as set forth.

2. The axle and the packing-ring '0, having the slot 0, combined with the circular plate 0 and screw 0, substantially as set forth.

3. The axle and the packing-ring O, having the slot 0, combined with the plate 0, screw c, and spring D, substantially as specified.

4. The axle-box A, combined with the interior end stop, E, and bolts 6, substantially as set forth.

In testimony whereof I my hand and seal.
